Firefox 10 Arrives Today with Extended Support for Businesses. Though the software does bring an array of tweaks and enhancements for both users and developers, it's perhaps most notable for the fact that it marks the debut of the business-oriented Extended Support Release (ESR) program. One can check out what’s new and known issues for this version of Firefox by reading Mozilla's release notes. Perhaps the most important change from a user's perspective is that add-ons and themes are assumed to function, rather than not function as assumed by previous Firefox versions, meaning that the update process won't leave a user with familiar extensions disabled and needing updates.

The transition from Firefox 9.0.1 to 10 has been all that smooth. The biggest issue was with Java. My wife logs into work using a Java based Citrix connection on a Debian Squeeze computer using Iceweasel and OpenJDK with the Icedtea plugin. What worked in version 9, crashes with version 10. Firefox from Mozilla is similarly affected.

The only way I got things to work was to use Sun's (Oracle's) Java from java.com. What a mess.
